Segmentation fault in PyArray_Item_INCREF
I embed Python into cpp, and need to use numpy in the embeded python-shell. I get "Segmentation fault" while importing numpy in the second session with python-shell, and the first session with python-shell is ended by Ctrl-D. The following cpp code recall the "Segmentation fault" error.
Using Ubuntu 14.04.4 LTS(64 bit), Python3.4.3, gcc4.8.4, numpy1.11.0
//c_py.cpp
#include <stdio.h>
#include "Python.h"
void callpy(int argc, char**argv);
int main(int argc, char**argv)
{
while(true)
{
callpy(argc,argv);
printf("\nFinish one call. Do something else. Wait.\n");
getchar();
}
return 0;
}
void callpy(int argc, char**argv)
{
Py_Initialize();
Py_Main(argc,(wchar_t**)argv);
Py_Finalize();
}
I gdb it and got the following:
$ gdb ./c_py
GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1
This GDB was configured as "x86_64-linux-gnu".

Is there something wrong with NPY_COPY_PYOBJECT_PTR?
NPY_COPY_PYOBJECT_PTR copy PyObject pointer from src to dst, so src and dst need to be pointer to PyObject pointer.
NPY_COPY_PYOBJECT_PTR is defined in npy_cpu.h
#define NPY_COPY_PYOBJECT_PTR(dst, src) memcpy(dst, src, sizeof(PyObject *))
but in
34 NPY_COPY_PYOBJECT_PTR(&temp, data);
data is char*. Perhaps data would be &data.
But I get some other Segmentation faults after modifying to NPY_COPY_PYOBJECT_PTR(&temp, &data);
well, deep segfault, deep night.
